Description:
Several vulnerabilities were reported in PostgreSQL. A remote authenticated user can gain elevated privileges on the target database. A remote authenticated user can cause denial of service conditions.
A remote authenticated user can invoke certain index functions to gain elevated privileges [CVE-2007-6600]. The VACUUM and ANALYZE functions can be executed with superuser privileges. The SET ROLE and SET SESSION AUTHORIZATION functions can be accessed within index functions.
A remote authenticated user can submit SQL queries containing specially crafted regular expressions to cause the database to enter an infinite loop, consume excessive memory, or crash [CVE-2007-4772, CVE-2007-6067, CVE-2007-4769].
A remote authenticated user can invoke DBLink functions (combined with local trust or ident authentication) to gain superuser privileges [CVE-2007-3278, CVE-2007-6601].
|
Impact:
A remote authenticated user can gain elevated privileges on the target database.
A remote authenticated user can cause denial of service conditions on the target system.

Red Hat Security Advisory
Synopsis: Moderate: postgresql security update
Advisory ID: RHSA-2008:0039-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0039.html
Issue date: 2008-01-11
CVE Names: CVE-2007-3278 CVE-2007-6600 CVE-2007-6601
=====================================================================
1. Summary:
Updated postgresql packages that fix several security issues are now
available for Red Hat Enterprise Linux 3.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
3. Description:
PostgreSQL is an advanced Object-Relational database management system
(DBMS). The postgresql packages include the client programs and libraries
needed to access a PostgreSQL DBMS server.
A privilege escalation flaw was discovered in PostgreSQL. An authenticated
attacker could create an index function that would be executed with
administrator privileges during database maintenance tasks, such as
database vacuuming. (CVE-2007-6600)
A privilege escalation flaw was discovered in PostgreSQL's Database Link
library (dblink). An authenticated attacker could use dblink to possibly
escalate privileges on systems with "trust" or "ident" authentication
configured. Please note that dblink functionality is not enabled by
default, and can only by enabled by a database administrator on systems
with the postgresql-contrib package installed.
(CVE-2007-3278, CVE-2007-6601)
All postgresql users should upgrade to these updated packages, which
include PostgreSQL 7.3.21 and resolve these issues.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
